A41606-ENC-01

The Astek A41606-ENC series products utilize state of the art Gen2 Serial Attached SCSI (SAS) expanders operating at 6Gbps, to provide high-density storage enclosures with industry leading performance. Based on Astek’s innovative SAS expander module, combined with a precision machined chassis, and a unique 'sled-less' disk mounting mechanism. these enclosures can hold between sixteen and twenty-four 2.5” hard disks.The A41606-ENC provides two external SAS x4 wide-port input/output connections per expander, with each wide port supporting up to 24Gbps of I/O. Each port can be connected either to a host or another A41606-ENC, allowing system designers to cascade multiple enclosures to further increase the total available storage.

As the Astek enclosure is based on an ANSI T10 SAS 2.0 compliant bus expander, it supports direct connection of both enterprise class SAS disks and low-cost Serial ATA (SATA) disks. The expander chipset onboard transparently bridges SATA to SAS. The SAS protocol also natively supports hot-swap of disks without requiring special software. When configured with dual SAS expanders, the A41606-ENC supports both ports of true SAS disks, providing independent I/O paths from host to disk, and allowing system designers to support true redundant access for high-reliability systems.
